is the BSOD code the 0x0.000000124?

I think its 124? BSOD 124

Continue increasing the vcore until you're able to run prime blend. Make sure the Dram voltage is at stock, sometimes due to vdrop the RAM voltage can be lower, so double check that.

Well basically I'm getting BSOD 124 from voltages 1.25-1.350

Right now I'm at 1.350 and testing it.

I disabled CPU thermal throttling. Is that right?

Also ram is at 9-9-9-24 now

Keeps BSOD on prime 95 sometimes within seconds and sometimes within 1-3 mins. Seems like I'm close so im trying 1.35 right now. I think my chip is voltage hungry

Ok so seems like it works at 1.35 volts and 4.5

Ran prime95 for about 5 or 6 mins no BSOD

Everything before 1.35 volts was giving me BSOD 124

Temps reached 73*C on hottest core.

Looking good, try running prime a little longer and if it fails increase the vcore. Check out the Sandy Stable Club when you get a chance, there is loads of info in the OP. link is in my sig.

Sweet ok trying it longer. I plan to get this to at least 4.8 though. I'd love for it to be under 75* but I'm not sure.

I think Im going to return my hyper 212+ tomorrow for a noctua nd h14 or whatever it is with the dual fans and the dual heatsinks. It seems a bit big though. Not sure if it will fit on my mobo.

Should I change any of the other volts when I try to get to 4.8? How do I get to 4.8? would I just change the vcore and the multiplyer at this point?

4.5 is kinda low for me atm, I'd rather just run 4.6 auto settings since its higher. I dunno

I just got BSOD 124 about 5-10 mins into prime95... Sigh. Upped the voltage to 1.360 and testing now. Hopefully my vcore doesnt have to be too high. It seems like my chip sucks.

Alright so far I'm looking pretty decent here.

45 multiplyer
1.360 Volts
going from 1.360-1.368
All other voltages are Auto
Spread spec diabled
PLL overvoltage disabled
LLC at level 2 still
250
250
250
Ram is still at 9-9-9-24
Thermal throttling disabled

DRAM freq is at 800 MHz is that good aswell?

Temps are getting a little up there with top temp at 75*C
Its been running for 10+ mins so far no BSOD

Maybe I'm on wrong Prime95 settings rofl. I'm getting this other test that just made my CPU really hot rofl FFT length 8K? what is this? It bumped my temps to 78*C



1.36 volt
4.5

30 mins prime95

A bit hot for my liking... Does this mean I cant even go higher? Because clearly if I bump the vcore any more it will get hotter. And to get higher multiplier I need to bump the vcore. So I think 4.8 4.9 5.0 are out of reach untill I get some better cooling? Is this right?

read this and then you can make a decision on how high you want to go:



****Max Safe Voltage and Temps****


Before I go into this, I just want to say that this is my OWN opinion and take it as you will.

No one is absolutely certain of what the safe vcore is for the sandybridge chips. What I can tell you is that many say the max safe vcore for these chips are 1.3 region, however, intel states that the max 'VID' is 1.52 and many say that around 1.4 if your on air and 1.45 should be the max if your running water cooling. Personally I will not go above 1.5v for 24/7 with these chip but that is totally upto you. The main thing to understand is that 'YOU' have to come up with the conclusion of what the max is. That way no one is blamed if the chip degrades (none reported so far, even with so called 'high 1.4+ vcore')

Those that have killed or degraded their cpu's have done so through either by their own fault, running sucide runs with crazy voltages and by not having substantial cooling for their overclocks and voltage or for reasons like their mobo or PSU causing shorting and also BIOS bugs.

Please remember that not all chips are the same, some can do high overclocks with low voltage some cannot.

Regarding temps, CPU throttles at 95c, some say keeping it below 85c is good, some say keeping it below 80 is better, other's say below 75c is really good and there are quite a few that say 70c should be the max. Which ever one your comfortable with and if you have substantial cooling, YOU DECIDE YOUR MAX, just remember it throttles at 95c. If for example you hit 85c in stress testing then in everday usage it shouldn't be higher than 75c which I think is fine, I personally like to keep mine below 70/75c during general everyday usage



I say carry on until you start hitting 85c in realtemp and keep the voltage under 1.45v for air cooling, that's my opinion.

By the way, it's looking good so far.
